Biography

I obtained an MSc degree with Distinction in Communications Engineering from the University of Manchester in 2007, followed by a PhD in Terahertz Monolithic Oscillators and Integrated Circuits from the University of Glasgow in 2012. I completed my PhD in under three years, producing 24 publications during that time.

In August 2011, I began working as a Postdoctoral Research Assistant, and later as a Postdoctoral Research Associate, at the University of Glasgow, focusing on terahertz imaging systems. In January 2014, I joined the National Physical Laboratory (NPL) as a Higher Research Scientist, where I led research on antennas, over-the-air (OTA) testing, ultrafast calibration service, and on-wafer measurements.

I returned to the University of Glasgow in August 2017 as a Lecturer and founded the Microwave and Terahertz Electronics (MaTE) group. I was promoted to Professor of Microwave Engineering in August 2023. Since May 2021, I have also served as Director of the Centre for Advanced Electronics (CAE) and established the Glasgow/Keysight-joint TiC6G lab.

I was a Visiting Lecturer at the University of Strathclyde (2022–2025) and a Visiting Researcher at the Advanced Technology Institute (ATI) at the University of Surrey (2017). I serve as Co-Chair of EuMiC 2026 and Chair of the 106th ARFTG Spring Conference in 2026. I was a member of the European Microwave Association (EuMA) General Assembly, representing Group 4 (United Kingdom, Ireland, Gibraltar, and Malta) from 2018 to 2021. Additionally, I served as Chair of Workshops and Short Courses at EuMW 2021 and as an Associate Editor for Royal Society Open Science from 2017 to 2023.

PhD projects

Making the quantum computers wireless

The ENIAC, the first computer invented 75 years ago, occupied a whopping 170 square meters and weighed nearly 50 tonnes. At that time, nobody could have imagined the incredible evolution computers would undergo to reach their current form. Quantum computing, believed to be one of the most significant revolutions of the 21st century, is still in its early stages, encountering similar challenges faced by the first computers half a century ago: bulkiness, high cost, and operational difficulties. However, here at Glasgow University, we are fearless and ambitious!

Thanks to the generous funding provided by EPSRC's WiQC and EPIQC projects, we are poised to take a daring yet potentially rewarding step towards the next generation of quantum computers: developing wireless quantum computing. Imagine that! Would you like to be a part of this groundbreaking endeavor? If so, please reach out to us and let's shape the future together.

Pushing the limits of low noise amplifiers: from semiconductor materials, device physics, nanofabriacation to circuit design

Low noise amplifiers (LNAs) play a crucial role in various RF systems, including communications, RADAR, astronomy observation, and remote sensing. They are widely recognized as essential components. Traditionally, the key performance parameters of LNAs have encompassed aspects such as noise figure, gain, linearity, and bandwidth. However, the emergence of quantum computer systems has introduced a new performance factor: DC power consumption. This addition has made the development of LNAs even more challenging and demanding.
In this exciting project, you will have the opportunity to leverage the world-leading nanofabrication and test facilities at Glasgow University, specifically the JWNC and ESDC. By capitalizing on these cutting-edge resources, you will be able to contribute to and build upon Glasgow University's esteemed legacy in the field of transistors. This is an exceptional chance to advance the field and see Glasgow University's expertise in transistors flourish once again.

GaN-based diodes and tranistors for water and gas sensing

The presence of ionic pollution in water and high concentrations of gases, vapors, and volatile organic compounds in the air pose significant threats to human health, food safety, and the environment. To address these concerns, GaN-based field-effect transistor (FET)-based sensors have emerged as a promising solution, thanks to their remarkable sensitivity to surface charge. However, current technologies utilizing GaN transistors typically require tens of milliwatts of power, which is often unsustainable for many applications.

In this project, our primary objective is to substantially reduce the power consumption of these sensors by at least two orders of magnitude. This will be achieved through a comprehensive co-optimization approach that encompasses device design, circuit optimization, and system integration. By synergistically enhancing the efficiency of each element, we aim to pave the way for highly efficient and sustainable sensor solutions that address the critical challenges posed by ionic pollution, gas concentrations, vapors, and volatile organic compounds.

Compact monolithic integrated circuits for Beyond 5G/6G wireless communications

Since the widespread rollout of commercial 5G networks starting in 2019, the research focus on next-generation mobile communications has become paramount for both academia and industry. A critical challenge in advancing future communication systems lies in developing highly efficient RF front-ends or transceivers. As the operating frequencies of these systems shift into the millimeter-wave domain, such as at 30 GHz and above, electronic devices like amplifiers and integrated circuits for passive components face various performance degradation issues. These include reduced efficiency, higher power consumption, and limitations in integration capabilities.

In this project, you will have the unique opportunity to leverage Glasgow University's world-leading nanofabrication and test facilities, specifically the JWNC and CAE. By harnessing these state-of-the-art resources, you will devise, fabricate, and test compact transceivers operating at frequencies of 110 GHz and beyond. This endeavor will enable us to overcome the current limitations and pave the way for high-performance transceivers that meet the demands of future communication systems. Join us in pushing the boundaries of mobile communications and shaping the future of wireless technology.

Development of wireless charging technology for wireless sensor nodes
Wireless sensor nodes (WSN) have found widespread applications in various fields, including environment monitoring, building structural health checks, and personal medical diagnosis. However, most sensor nodes currently rely on bulky built-in batteries that have limited lifespans. The cost and feasibility of battery replacement can be prohibitive in certain scenarios. Over the past decade, researchers have explored different energy harvesting approaches, such as solar, thermal, and acoustic energy conversion, to power WSNs. However, these methods encounter limitations related to weather conditions, size, distance, and communication.

RF/microwave signals, such as GPS, WiFi, and 4G/5G, are omnipresent and offer advantages like low attenuation in air and resistance to weather conditions. These characteristics make them suitable for long-distance applications. However, RF/microwave signals suffer from high losses in water or inside human bodies. To address this issue, different media, such as ultrasound, must be implemented. In this project, we will investigate a novel hybrid microwave-ultrasound transducer that serves the dual purpose of energy harvesting and wireless communications. Our research will focus on overcoming challenges related to RF/microwave sensing, RF/microwave to ultrasound frequency conversion, and ultrasound transducer efficiency.

The selected candidate will delve into the exploration of new materials, device modeling, circuit design, and micro/nano fabrication techniques. Ultimately, we aim to develop a hybrid transducer that integrates CMOS sensors and can be utilized for underwater monitoring and/or medical diagnosis. Through this interdisciplinary endeavor, we will advance the field of wireless sensor technology, opening up new possibilities for sustainable energy harvesting and efficient wireless communication in challenging environments.
